Sons of Liberty Gun Works MK1 CAR SBR 11 .5" Bbl 5.56 P3 Chrome Lined MK1 Cable Management Rail MK1-CAR-556-115CL-SBR-A-FDE

The Sons of Liberty Gun Works MK1 CAR SBR is built for shooters who demand a compact 5.56 rifle with serious performance and confidence-inspiring control. Its 11.5 inch P3 chrome lined barrel is designed to help deliver dependable operation and extended barrel life, while the MK1 Cable Management Rail keeps the front end clean, organized, and ready for accessories.

At the heart of the platform is the Drivelock rail system, engineered for exceptional rigidity with steel anti-rotational dowels that strengthen the connection between the upper receiver and handguard. That rock-solid foundation helps support consistent optic alignment and stable mounting across the full rail length. The upper receiver raceways feature a specialized coating to reduce carrier drag, promoting smoother cycling and reduced wear over time.

With scalloped Picatinny slots, deep cable routing channels, and a compact form factor weighing just under six pounds, the MK1 CAR SBR balances maneuverability with durability. It is a purpose-built rifle for users who value reliability, refined handling, and a thoughtfully engineered design that performs when it matters most.
